Szczegółowe wyjaśnienie:
3³⁻⁶ * 2⁻³ = 3⁻³ * 2⁻³ = ( 3 * 2)⁻³= 6⁻³ = ( 1/6)³ = 1/216
=======================
∛(-64/125) + √(64/25)+∛(50*20)=
= - 4 /5 +8/5 + ∛1000=
= 4/5 + 10 =
= 10 i 4/5
========================================
[ 4 * 6 * 10⁶⁺⁽⁻¹²⁾ ]/ [ 9*8 * 10⁻²⁸⁺²⁴]=
= [ 24 * 10⁻⁶] / [ 72 * 10⁻⁴ ]=
skracamy 24 i 72 przez 24
= 1/3 * 10⁻⁶⁻⁽⁻⁴⁾ = 0,333... * 10⁻⁶⁺⁴ = 0,333...*10⁻² =
= 3,333...* 10⁻¹ * 10⁻² = 3,(3) * 10⁻¹⁺⁽⁻²⁾ = 3,(3) * 10⁻³
=======================================
(2⁻⁴)⁴ : 8⁻⁶ = 2⁻¹⁶ : (2³)⁻⁶ = 2⁻¹⁶ :2⁻¹⁸ =
= 2⁻¹⁶⁻⁽⁻¹⁸⁾ = 2⁻¹⁶⁺¹⁸ = 2² = 4
